I wrote a query to list all posts for a given user by user id.
SELECT id, PostTypeId, posts.Title, Body, CreationDate FROM posts WHERE posts.OwnerUserId = 9872
which could be found by search the following keywords
list all posts
nevertheless, I cannot find that query by more specific keywords
list all posts by user
I guess it is not convenient for those users might want to find existing queries.
I am not sure if this could be considered as feature request, please correct if necessary.
